Perfect spot to push?!?!

[LAgambol]

10/20 NL Live
Villain is solid player, semi TAG
Hero's been playing semi-LAG, but nothing major out of line

Villain has 2.5K, Hero covers
Villain raises to 120 from MP, CO +1 calls, Hero in CO calls with 6d5d

Flop:
8 4 2
Villain bets 200, Co+1 folds, Hero makes it 750, villain calls
Turn: 9
Villain checks, Hero bets 1500

after the villain just flat called and checked the turn, i thought this would be a prime spot to push...what do you think? thoughts on all streets appreciated.
